CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 4.46,569,dated February 17, 1891.

Application filed September 29, 1390- Serial No. 366,516. (No model.)

To ctZZ whom it may concern.-

Be it known that I, JOHN PLAYER, a citizen of the United States, residing at Topeka, Shawnee county, Kansas, h ave invented a new and useful Improvement in Car-l3rakes, of which the following is a specification.

My invention has particular reference to the form of the compression members of a trussed brake-beam, to the strut used therein, and to the combined brake-heads and sockets for receiving the ends of the compression members; and the invention consists in the features and details of construction hereinafter described and claimed. a

In the drawings, Figure 1 is a plan view of myimproved brake-beam. Figs. 2, 23, 1-, and 5 are cross-sections of various forms of compression members. Fig. 6 is a plan view of a portion of a beam, having such members made of angle-iron; and Fig. 7, a cross-section on line '7 7 of Fig. 6, looking in the direction of the arrows.

The compression members A (shown in Fig.

1) are made of tubing or gas-pipe, of any suitable dimensions, and cored, if necessary, to admit of the passage of the truss-rod. A strut 3 is provided, made of any suitable material, and substantially T-shaped, as shown, its arms being bent downward and cored to form sockets to receive the ends of the compression members A. This strut is cored at?) to allow the truss-rod C to pass through, and, extending beyond this rod, is forked,as shown at b, to receive the brake-lever. I then make the combined brake-heads and socket-pieces D. These are made substantially as shown in Fig. 1, wherein they consist of a block, formed to receive the brake-shoe, and a socket-piece (l integral therewith, and extending at airailgle from one side thereof and cored to receive the end of the compression member. A hole (1 is also made to allow the truss-rod to pass through the brake-head.

The parts are put together as follows: The compression members are inserted into the sockets in the strut, the brake-heads and sockets are passed over the ends of such 1nembers, and the truss-rod being passed through the brake-heads and strut is fastened securely in place by means of nuts 0, whereby the parts are held firmly together. The members may be firmly secured in the sockets and strut or simply inserted therein and held by the nuts 0 c, as desired.

In Figs. 2 to 5 are shown different forms of compression members. Fig. 2 is a cross-section of the member shown in Fig. 1. Fig. 3 shows a member made of angle-iron. Figs. 4:

and 5 are members made of different commercial forms of iron. Any of these forms or others may be used, as desired.

In Figs. 6 and 7 is illustrated a beam with angle-iron compressing members, the advantage of this being that the truss-rod passes between the legs of the iron without cutting the member, thereby avoiding weakening it. The brake-heads are of course to be cored to [it whichever form of compression member is used. The brake-shoes are attached directly to the combined brake-heads and sockets D.

I claim 1. In a brake-beam, a brake-head D, having a socket (Z integral therewith and extending laterally at an angle thereto, substantially as describ d.

2. In a brake-beam, the combination of the compression members A, the T-shaped strut B, the combined brake-heads and sockets D, and the truss-rod c, passing through the strut, compression members, and brake-heads, and secured by nuts 0 or other suitable means, substantially as described.

In a brake-beam, a strut B, cored to receive thecompression members and truss-rod and extending beyond such rod to receive the brake-lever, substantially as described.

i. In a brake-beam, the'combination of compression members A, combined brake-heads and sockets D a strut B, and a truss-rod C, the strut extending beyond the truss-rod to support the brake-lever, substantially as described.

5. In a brake-beam, the combination of compression members A, made of angle-iron, combined brake-heads and sockets D, a strut B, and a truss-rod passing through the strut and brake-heads and between the legs of the compression members, whereby any cutting of such members is avoided, substantially as described.
